A barrister's tactic at the end of a rape trial has prompted women to share pictures of their underwear online.

A 27-year-old man was found not guilty of rape after a trial last week after his defence barrister introduced the 17-year-old complainant's lace thong in her closing speech.

Women are now sharing pictures of their own underwear on social media with the hashtag #ThisIsNotConsent.

One woman tweeted: "Can we get a list of knickers we're not allowed to wear if we dont wanna be raped?"

The Irish Examiner reported that Barrister Elizabeth O’Connell told jurors to take the underwear the girl wore on the night of the alleged rape into consideration.

She said: "You have to look at the way she was dressed. She was wearing a thong with a lace front.”

Noeline Blackwell, head of the Dublin Rape Crisis Centre, told The Independent: "The reference to the girl’s underwear and the assumption and inference that the jury was being invited to draw – that because she was dressed like that she was asking for sex – does not surprise us.”

Women have been saying the defence used by the barrister amounts to victim blaming. They have been asking others to join them in spreading the hashtag with their own pictures.
